A pulley assembly is provided for an operating cord. The pulley has a body with a rotational axis and an annular outer surface concentric with the rotational axis. A cord retention member has a surface to be situated around the annular outer pulley surface in operative relationship with the pulley and extending more than 180 DEG around the annular outer pulley surface. Structure is provided on the pulley and cord retention member to cooperate with the cord so that the cord prevents separation of the pulley and cord retention member from their operative relationship.
